class representing a polygon from the SBML render extension
The Polygon is very similar to the RenderCurve class. The only difference is that in the polygon the end point of the last element in the curve segment list is automatically connected to the start point of the first element.
Since a polygon is a closed shape and doesn't really have a start or an end, it does not get decorations as the RenderCurve does.
So a polygon is always closed and can therefor have a fill style and fill style related attributes. Those attributes are inherited from Polygons base class GraphicalPrimitive2D.

appendAnnotation(SBase self, XMLNode annotation)int appendAnnotation(SBase self, string annotation)
int
This method has multiple variants that differ in the arguments they accept. Each is described separately below.
appendAnnotation(XMLNode annotation)
Appends the given annotation
to the 'annotation' subelement of this object.
Whereas the SBase 'notes' subelement is a container for content to be shown directly to humans, the 'annotation' element is a container for optional software-generated content not meant to be shown to humans. Every object derived from SBase can have its own value for 'annotation'. The element's content type is XML type 'any', allowing essentially arbitrary well-formed XML data content.
SBML places a few restrictions on the organization of the content of annotations; these are intended to help software tools read and write the data as well as help reduce conflicts between annotations added by different tools. Please see the SBML specifications for more details.
Unlike SBase.setAnnotation() or SBase.setAnnotation(), this method allows other annotations to be preserved when an application adds its own data.

This method has multiple variants that differ in the arguments they accept. Each is described separately below.
appendNotes(string notes)
Appends the given notes
to the 'notes' subelement of this object.
The content of the parameter notes
is copied.
The optional SBML element named 'notes', present on every major SBML component type, is intended as a place for storing optional information intended to be seen by humans. An example use of the 'notes' element would be to contain formatted user comments about the model element in which the 'notes' element is enclosed. Every object derived directly or indirectly from type SBase can have a separate value for 'notes', allowing users considerable freedom when adding comments to their models.
The format of 'notes' elements must be XHTML 1.0. To help verify the formatting of 'notes' content, libSBML provides the static utility method SyntaxChecker.hasExpectedXHTMLSyntax(); however, readers are urged to consult the appropriate SBML specification document for the Level and Version of their model for more in-depth explanations. The SBML Level 2 and 3 specifications have considerable detail about how 'notes' element content must be structured.

disablePackage(SBase self, string pkgURI, string pkgPrefix)int
Disables the given SBML Level 3 package on this object.
This method disables the specified package on this object and other objects connected by child-parent links in the same SBMLDocument object.
An example of when this may be useful is during construction of model components when mixing existing and new models. Suppose your application read an SBML document containing a model that used the SBML Hierarchical Model Composition (“comp”) package, and extracted parts of that model in order to construct a new model in memory. The new, in-memory model will not accept a component drawn from another SBMLDocument with different package namespace declarations. You could reconstruct the same namespaces in the in-memory model first, but as a shortcut, you could also disable the package namespace on the object being added. Here is a code example to help clarify this:
import sys import os.path from libsbml import * # We read in an SBML L3V1 model that uses the 'comp' package namespace doc = readSBML('sbml-file-with-comp-elements.xml'); # We extract one of the species from the model we just read in. s1 = doc.getModel().getSpecies(0); # We construct a new model. This model does not use the 'comp' package. newDoc = SBMLDocument(3, 1); newModel = newDoc.createModel(); # The following would fail with an error, because addSpecies() would # first check that the parent of the given object has namespaces # declared, and will discover that s1 does but newModel does not. # newModel.addSpecies(s1); # However, if we disable the 'comp' package on s1, then the call # to addSpecies will work. s1.disablePackage('http://www.sbml.org/sbml/level3/version1/comp/version1', 'comp'); newModel.addSpecies(s1);

implementation of a 2D transformation matrix.
The Transformation2D class represents a 2D transformation. it is derived from Transformation and inherits all the attributes of a 3D transformation. In addition is provides new methods to explicitly get and set 2D transformation properties. A 2D transformation normally consists of a 3x3 matrix, but since the last row is always 0 0 1, this is reduced to a 6 value array.
Using one of the new 2D specific functions to set the matrix always updates the 3D matrix automatically and vice versa, so the 2D data and the 3D data inherited from Transformation should always be consistent. Python method signature(s):

getResourceBiologicalQualifier(SBase self, string resource)long
Returns the MIRIAM biological qualifier associated with the given resource.
In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The latter kind is used to qualify the relationship between a model component and a biological entity which it represents. Examples of relationships include 'is' and 'has part', but many others are possible. MIRIAM defines numerous relationship qualifiers to enable different software tools to qualify biological annotations in the same standardized way. In libSBML, the MIRIAM controlled-vocabulary annotations on an SBML model element are represented using lists of CVTerm objects, and the the MIRIAM biological qualifiers are represented using valueswhose names begin with BQB_
in the interface class libsbml.
This method searches the controlled-vocabulary annotations (i.e., the list of CVTerm objects) on the present object, then out of those that have biological qualifiers, looks for an annotation to the given resource
. If such an annotation is found, it returns the type of biological qualifier associated with that resource as a valuewhose name begins with BQB_

In MIRIAM, qualifiers are an optional means of indicating the relationship between a model component and its annotations. There are two broad kinds of annotations: model and biological. The former kind is used to qualify the relationship between a model component and another modeling object.

getSBOTerm(SBase self)int
Returns the integer portion of the value of the 'sboTerm' attribute of this object.
Beginning with SBML Level 2 Version 3, objects derived from SBase have an optional attribute named 'sboTerm' for supporting the use of the Systems Biology Ontology. In SBML proper, the data type of the attribute is a string of the form 'SBO:NNNNNNN', where 'NNNNNNN' is a seven digit integer number; libSBML simplifies the representation by only storing the 'NNNNNNN' integer portion. Thus, in libSBML, the 'sboTerm' attribute on SBase has data type int
, and SBO identifiers are stored simply as integers. (For convenience, libSBML offers methods for returning both the integer form and a text-string form of the SBO identifier.)
SBO terms are a type of optional annotation, and each different class of SBML object derived from SBase imposes its own requirements about the values permitted for 'sboTerm'.

Python method signature(s):
unsetName(SBase self)int
Unsets the value of the 'name' attribute of this SBML object.
Most (but not all) objects in SBML include two common attributes: 'id' and 'name'. In contrast to the 'id' attribute, the 'name' attribute is optional and is not intended to be used for cross-referencing purposes within a model. Its purpose instead is to provide a human-readable label for the component. The data type of 'name' is the type string
defined in XML Schema. SBML imposes no restrictions as to the content of 'name' attributes beyond those restrictions defined by the string
type in XML Schema.
The recommended practice for handling 'name' is as follows. If a software tool has the capability for displaying the content of 'name' attributes, it should display this content to the user as a component's label instead of the component's 'id'. If the user interface does not have this capability (e.g., because it cannot display or use special characters in symbol names), or if the 'name' attribute is missing on a given component, then the user interface should display the value of the 'id' attribute instead. (Script language interpreters are especially likely to display 'id' instead of 'name'.)
As a consequence of the above, authors of systems that automatically generate the values of 'id' attributes should be aware some systems may display the 'id''s to the user. Authors therefore may wish to take some care to have their software create 'id' values that are: (a) reasonably easy for humans to type and read; and (b) likely to be meaningful, for example by making the 'id' attribute be an abbreviated form of the name attribute value.
An additional point worth mentioning is although there are restrictions on the uniqueness of 'id' values, there are no restrictions on the uniqueness of 'name' values in a model. This allows software applications leeway in assigning component identifiers.
